SynopsisThe remote FTP server is affected by a buffer overflow vulnerability.
DescriptionAccording to its banner, the remote FTP server is a version of VxWorks ftpd between 5.4 and 5.4.2. Such versions are known to be affected by a buffer overflow that can be triggered with an overly-long 'CEL' command. This problem is similar to the 'aix ftpd' overflow but on embedded VxWorks-based systems like the 3Com NBX IP phone call manager and seems to cause the server to crash.
SolutionIf you are using an embedded VxWorks product, please contact the OEM vendor and reference WindRiver field patch TSR 296292. If this is the 3Com NBX IP Phone call manager, contact 3Com.
